Place drm_event_vblank in a new union that includes that and a bare
drm_event structure. This will allow new members of that union to be
added in the future without changing code related to the existing vbl
event type.
Assignments to the crtc_id field are now done when the event is
allocated, rather than when delievered. This way, delivery doesn't
need to have the crtc ID available.
v2:
* Remove 'dev' argument from create_vblank_event
It wasn't being used anyways, and if we need it in the future,
we can always get it from crtc->dev.
* Check for MODESETTING before looking for crtc in queue_vblank_event
UMS drivers will oops if we try to get a crtc, so make sure
we're modesetting before we try to find a crtc_id to fill into
the event.

With the atomic API, it is possible that a single commit affects
multiple crtcs. If the user requests an event with that commit, one
event will be sent for each CRTC, but it is not possible to distinguish
which crtc an event is for in user space. To solve this, the reserved
field in struct drm_vblank_event is repurposed to include the crtc_id
which the event is for.
The DRM_CAP_CRTC_IN_VBLANK_EVENT is added to allow userspace to query if
the crtc field will be set properly.

Problem:
DMC can't set up from bootargs. For easy debug, we need
set a monitor from bootargs.
Solution:
Add a funciton for this feature. You can using following patten
to set up a DMC monitor:
dmc_montiro=[start_addr],[end_addr],[mask]
Example:
setenv initargs $initargs dmc_monitor=0x0,0x20000000,0xff58
This command set up monitor for following device on GXL:
